“…Excess energy in the feed reduces feed utilization that results the lower amount of protein and other essential nutrients available to the fishes (NRC 1993). Similar results were also found in studies carried out in different fishes such as in juvenile cobia, Rachycentron canadum (Sun et al2006); snakehead, Channa striata fingerling (Samantaray and Mohanty 1997); black catfish, Rhamdia quelen fry (Salhi et al 2004); which is supported by the present results. Temperature also have a marked influence on the better feed efficiency.It is generally found that fish are able to eat maximum level of feed at a given temperature condition when feed supply are unlimited (Amin et al 2014 ).…”

“…Phillips (1972) found that increase in weight gain/ growth rate up to a certain energy level and decreasing thereafter may be the result of an increase in the energy requirement of fish to get rid of excess toxic nitrogenous waste production due to increased rate of amino acid breakdown as temperature increases. Similar results were also found in studies carried out in other fishes like Channa striata fingerling (Samantaray and Mohanty 1997); black catfish, Rhamdia quelen, fingerlings (Meyer and Fracalossi 2004;Salhi et al2004), red drum (McGoogan and Gatlin 1999). A positive relationship between energy requirement and the temperature was found by several researcher, i.e., as water temperature increases, the energy requirement of fish also increases within an optimum temperature range of water and decreases there after (Jobling 1994;De Silva and Anderson 1995;Bailey and Alanärä 2006,Person-Le Ruyet et al 2006, Katersky and Carter 2007, which very well supports our finding.The possible reason for increased energy requirement at high temperature is due to the increased metabolic rate (Katersky and Carter 2007).…”

A 60-days feeding trial was conducted to study the dietary energy requirement of Pangasianodon hypophthalmus (Sauvage1878) juveniles reared either at ambient (24.5°C) or higher temperature (32°C) and fed with one of the four diets having dietary energy content of 342 Kcal. 100 g -1 (T1), 379 Kcal. 100 g -1 (T2), 428.5 Kcal. 100 g -1 (T3) and 448.6 Kcal. 100 g -1 (T4). Juveniles of P. hypophthalmus with amean weight 4.27±0.12 to 4.40±0.10 g was stocked in 24 uniform size plastic rectangular tanks in triplicates with 10 fish per tank following a 2x4 factorial design. Growth performance and nutrient utilization of P. hypophthalmus were higher at the dietary energy content of 428.5 Kcal. 100 g -1 (T3) at both the temperatures. The body composition of P. hypophthalmus did not differ significantly (P>0.05) as the energy content of the diet increase. However, the tissue lipid content was significantly varied (P<0.05) at different temperature and energy levels. Based on the second order polynomial regression equation the dietary energy requirement of P. hypophthalmus was recorded to be 410 Kcal. 100 g -1 and 402.5 Kcal. 100 g -1 at 32°C and at ambient temperature(24.5°C), respectively.

“…It has been observed that low feed conversion ratio (FCR) and high growth rate of fish can be achieved if the P/E ratio of diet varies between 19.1 and 23.9 mg protein kJ -1 diet (Akand et al 1991, Samantaray andMohanty 1997). Therefore, it may be inferred that feed F 2 possessing the highest P/E ratio (18.3 ± 1.1 mg protein kJ -1 ; mean ± standard deviation) produced better growth response in C. catla and C. mrigala fingerlings as compared to the other diets.…”

. 2008. Supplementation of four non-conventional aquatic weeds to the basal diet of Catla catla and Cirrhinus mrigala fingerlings: Effect on growth, protein utilization and body composition of fish. Acta Ichthyol. Piscat. 38 (1): 21-27.Background. Our previous study has shown that four aquatic weeds viz. Asian watermoss, Salvinia cucullata; water spinach Ipomoea reptans; water chestnut, Trapa natans; and lesser duckweed, Lemna minor) from northeast India are important sources of proteins, vitamins and minerals, suitable for incorporation in fish diet. The aim of the present study was to compare the efficacy of these aquatic weeds based formulated diets on growth, feed utilization and nutrient turnover from feed to fish flesh of fingerlings of two species of Indian major carps: catla, Catla catla (Hamilton, 1822), and mrigal, Cirrhinus mrigala (Bloch, 1795). Material and Methods. The fingerlings were hand-sorted and distributed in 15 glass aquaria (each having 50 l capacity) at a stocking density of 5 fishes per aquarium. Five formulated diets (containing 26%-28% of crude protein approximately) were prepared and analyzed for proximate composition. The diets were fed to catla and mrigal fingerlings in triplicate treatments at the rate 3% of body weight for 60 days and fish performance in terms of growth, feed utilization and carcass composition was evaluated. Results. The whole body composition and energy content of C. catla fingerlings before and at the end of feeding trials did not differ significantly (P > 0.05), however, the proportion of crude lipid content was high when fed with diet F 2 (P < 0.05). In case of C. mrigala, crude protein, as well as lipid contents, were significantly higher in all the groups of fish at the end of experiment as compared to the initial fish. The hepatic-as well as the muscle tissues of catla and mrigal fingerlings fed the diet F 2 (containing I. reptans) displayed high contents of crude protein and vitamin E (P < 0.01). Interestingly, although no difference in muscle glycogen level in C. mrigala was observed irrespective of the diet fed however, muscle and liver glycogen contents in Catla catla fingerlings fed F 2 diet was significantly higher compared to glycogen contents of these tissues of initial fish or fish fed with control diet. Conclusions. Presently reported study suggests that I. reptans, being a rich source of nutrients, is suitable for incorporation in fish diet for C. catla and C. mrigala fingerlings.

Abstract:Six iso-energetic (352 kcal gross energy/100 g feed) and iso-nitrogenous (32% crude protein) experimental diets containing one of the four algae (Anabaena cylindrica, AN; Nostoc salbasa, NS; Spirulina platensis, SP; Westleopsis prolifica, WS) as the major dietary ingredient (40% of the total composition) or algal meal mixture with supplemental protein (AMM+PS) or only algal meal mixture (AMM) were tested against a control diet to find out the suitability of algal meal to develop practical diet for rohu fingerling. The experimental fish of average weight 2.0 ± 0.1 g were fed at a rate equaling 4% of body wt/day for 8 weeks at an experimental temperature of 28 ± 2°C. Significant (p<0.05) enhancement in growth rate was observed in the groups fed with WS (571%) followed by the groups fed with NS (517.6%) and SP (502.8%) as compared to that of the groundnut oil, rice bran and soybean meal based control diet (406.4%). Fingerlings fed with algal meal mixture (AMM) gained least (255.2%). Diet with WS performed well in terms of FCR, PER, HSI, MR and CF when AMM showed least efficiency. Fish fed with SP showed better protein utilization (ANPU%) as compared to the other dietary groups. Carcass protein was not affected by any diet. The MUFA and PUFA of liver and PUFA of muscle increased over the initial value fed with control and experimental diets. But the MUFA of muscle with these diets are less than the initial. The SFA content in all diets of both the tissues is either same or less than initial value except with AMM diet. The total n-3PUFA in liver increased with all diets over the initial value. But this increase in muscle was observed only with AN, NS, WS and AMM+PS diets. The n-6PUFA of liver and muscle remained either same or increased with all diets over initial value. This study showed that individual algal diets gave better result in growth performance and PUFA content. Among all the algal diets WS found to be the best.
